Description

Инобретеиие откоситс к обработке металлов давлением, н частности к штамиово оснастке дл обработки листового материала .The inventive approach is applied to the processing of metals by pressure, and in particular to the stam tooling for the processing of sheet material.

Цель изобретени - повышение точности изготавливаемых деталей.The purpose of the invention is to improve the accuracy of manufactured parts.

На фи1 1 изображена рабоча позици итамна последовательного действи ; на фиг. 2 сечение А-.Л на фи1. 1.Phi1 1 shows the working position of a series of sequential actions; in fig. 2 section A-.L on fi1. one.

Штамп содержит установленные в верхней части (не показана) пуансон 1 дл пробивки, ловители 2 -6, и пуансоны 7 и 8 дл вырубки контура детали, а в нижней части 9 1(1тамп содержит матрицу И).The stamp contains a punch 1 for punching installed in the upper part (not shown), catchers 2-6, and punches 7 and 8 for cutting the contour of the part, and in the lower part 9 1 (1 stamp contains the I matrix).

Штамп работает следующим образом.The stamp works as follows.

Полоса 11 поступает под пуансон 1, который пробивает в ней технологическое отверстие . При подаче на следуюпшй inar в это отверстие сначала входит ловитель 2, а пуансон I пробивает следую1цее отверстие. При следующем niare подачи в пробитые отверсти вход т уже два ловител 2 и 3, которые установлены относительно другThe strip 11 enters the punch 1, which pierces the technological hole in it. When feeding to the next inar in this hole, the catcher 2 first enters, and the punch I punches through the next hole. At the next feed niare, already two catchers 2 and 3 are inserted into the punched holes, which are set relative to each other.

Fixing to two catchers at once eliminates the accumulation of error due to the gap between the catcher and the hole, and the introduction of an additional iU) Lx catch allows you to even more increase the accuracy of the base due to a certain imposition of catches on the accuracy of their location, the accuracy of punching holes, etc. In connection with this, the strip 11 falls under the punches 7 and 8 with greater base accuracy, which determines an increase in the accuracy of the manufactured parts.

Firstly, 1b is located with its end closer to the matrix 10 than the previous one, so that you can see that catchers enter the holes in order to avoid smothering the material.
